How does Cassini communicate with Earth? The Radio Science Subsystem sent radio signals from Cassini to Earth using the spacecraft’s large radio dish called the high-gain antenna. En route, the radio signal interacted with Saturn’s moons, rings or Saturn’s atmosphere. The spacecraft’s high-gain antenna had to be pointed toward Earth in order to send its […]

Can a meteor hit the sun? No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t!
